Using a Timer To Delay for a few seconds before Printing

Posted on by TheBest355

Good morning All,

I have an issue that I have job cards that print which is fine but when navigating to the next screen it loads the job card but does not load the contents and displays the next print dialouge.

Ideally I want to press a button and it prints all the job cards but it is a limitation on PowerApps which I understand.

Therefore, at the moment when going to the job card, it the user presses print, then it prints and then should navigate to next job card and then print again but it prints before navigating and changes the contents on the job card after displaying the print dialogue.

Hope this makes sense?

There are multiple job cards that need to be printed and increment the job card value that displays the next job card.

It displays the job card number correctly but not the below contents unless print button is pressed.

If(
    !IsBlank(JobCardPage),
    Print()
);
Set(
    JobCardPage,
    JobCardPage + 1
);
Clear(ProdList);
Set(
    myVariable,
    ""
);
If(
    Label18.Text = "",
    Navigate(
        NoFurtherJobCards,
        ScreenTransition.Fade
    )
);
Print()
 
Thanks,
 
O

HI,

Let's assume each screen has a Print button that they COULD print, and also you have the scenario where they want to print them all

You can use the OnVisible Property, along with a Context Variable to do the printing.

Also, do you want to block the person from doing anything while its printing??? if so thats another thing secondary.

Steps

1) They Press Print on Screen 1 (and it's the Print All Option)

Now I don't use Print very much so I am not sure if it Blocks while printing or not. I am guessing Not??? Since its probably Queueing it via the Driver.

2) Kick off Print() for screen one

3) In Screen 2 (and do this for all of them)

In the OnVisible, check for a context variable called _ShouldIPrintOnLoad

in Screen 1, your navigate when you want to tell it to print would be

Navigate(Screen2, Transition.None, {_ShouldIPrintOnLoad: true/false }

When screen 2 loads AND is Visible, it will trigger itself to print

In the OnVisible

If (_ShouldPrintOnLoad, Print());

Or

If(_ShouldPrintOnLoad, Select(PrintButtonOnScreen2);

Cheers
